ABSTRACT

Assessment of existing components of power producing facilities is based on the probabilistic methods of the theory of structural reliability provided in Eurocodes and ISO standards. An example of quick-closing valves in a selected hydroelectric power plant indicates the assessment of reliability and prediction of remaining working life of a structural component for the considered model of corrosion. Moreover, assessment of reliability level of main steel structural members of existing industrial bridge for two alternatives of a cleaning machinery reveals rather low reliability level of some significantly deteriorated structural members of the industrial bridge in the power plant, and additional measures are to be applied.
